YouTube is a global online video‑sharing platform founded in February 2005 by three former PayPal employees—Steve Chen, Chad Hurley, and Jawed Karim—in San Jose, California. The service launched publicly in November 2005, allowing users to upload, view, and share videos. Its rapid growth was driven by an early focus on user‑generated content, a simple upload interface, and the ability to embed videos on external websites.

Development and impact
- Technical evolution: YouTube transitioned from Flash‑based video playback to HTML5 in 2015, improving compatibility across browsers and devices. Adaptive bitrate streaming (ABR) was introduced in 2013 to dynamically adjust video quality based on user bandwidth.
- Content ecosystem: The platform fostered varied content categories, including music videos, vlogs, educational tutorials, live gaming streams, and news. It has been instrumental in launching the careers of numerous digital creators and musicians.
- Economic model: Revenue primarily derives from advertising, subscription services (YouTube Premium, YouTube TV), and channel memberships. The Partner Program, as of 2024, requires at least 1,000 subscribers and 4,000 watch hours in the past 12 months for eligibility.
- Regulatory and policy landscape: YouTube has faced scrutiny regarding copyright enforcement (Content ID system, introduced 2007), child safety (COPPA compliance), and misinformation. The platform continuously updates its Community Guidelines and employs a mix of algorithmic and human moderation.
- Global reach: Available in 105+ countries and 80+ languages, YouTube reports over 2 billion logged‑in monthly users (2023 data). Mobile devices account for the majority of watch time.
Cultural significance
YouTube has reshaped media consumption patterns, contributing to the rise of “micro‑influencers,” user‑generated news, and participatory culture. Notable phenomena include viral music hits (e.g., “Gangnam Style” 2012), meme propagation, and the democratization of educational content via platforms such as Khan Academy and Crash Course.
